TDA2030 bridge 35 watt power amplifier Diagram Circuit
A very simple 35 watt power amplifier electronic project can be designed using the TDA2030 power audio IC. The TDA2030A is a monolithic IC in Pentawatt package intended for use as low frequency class AB amplifier.
The TDA2030A provides high output current and has very low harmonic and cross-over distortion. TDA2030 ICs connected in bridge mode.
This circuit require few external electronics parts and supports a 8 ohms load . This 35 watt power amplifier require a very good filtered DC power supply , that will provide an output voltage of +/- 16 volts .
Using this circuit you can design a very simple and efficiency subwoofer amplifier with a maximum output power of 35 watt power .
The device incorporates a short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. Also a conventional thermal shut-down system is also included .
However a heatsink must be used for the TDA2030 bridge circuit but for any reason, if the junction temperature increases up to 150oC, the thermal shut-down simply reduces the power dissipation and the current consumption.
